[0004] Although the above technical solution proposes to improve the stirring effect, the following defects still exist:

[0005] Existing polyurethane raw materials are mixed in larger quantities at one time to increase the production rate and ensure production volume. In this case, other chemical agents added to improve the properties of the polyurethane will also increase accordingly. The chemical agents added in proportion account for a small proportion, but the amount of the agents is large, which will make it difficult to mix the agents with a large amount of raw materials, increasing the mixing time and difficulty.

[0006] Therefore, a polyurethane insulation board raw material mixing and processing system is proposed. Summary of the invention

[0007] The purpose of the present invention is to provide a polyurethane insulation board raw material mixing and processing system. By using an adding mechanism, chemical agents can be periodically added to a mixing box so that the chemical agents will not accumulate and condense together, thereby allowing the chemical agents to be mixed into the polyurethane raw materials better and faster, and the discharge amount of the agent each time can be adjusted by an adjusting mechanism. By using a control mechanism, combined with the adjusting mechanism, the total amount of chemical agents in each operation of the device can be controlled so that the agents meet the needs, and the content of the chemical agents in the storage bottle can be seen through a colored cover and a color plate to remind the user to add the agent, thereby solving the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A polyurethane insulation board raw material mixing and processing system, comprising a mixing box, wherein support legs are fixedly installed at the four corners of the bottom of the mixing box, a protective shell is fixedly installed at the center of the bottom of the mixing box, a motor is fixedly installed in the protective shell, an output shaft of the motor passes through the bottom plate and the top plate of the mixing box and extends to the top of the mixing box, stirring rods are evenly distributed on the output shaft of the motor, a feed port is fixedly installed at the top of the mixing box, and an adding mechanism is fixedly connected to the top of the mixing box;

[0010] The adding mechanism includes a driving gear, a connecting cylinder and a medicine storage bottle, the driving gear is fixedly sleeved on the output shaft of the motor, the top plate of the mixing box is fixedly connected with a first hollow cylinder, the first hollow cylinder is movably sleeved with a driven gear, the driving gear and the driven gear are meshed with each other, the bottom of the driven gear is fixedly connected with a first inclined block, the connecting cylinder is fixedly connected to the top of the mixing box, an air bag is fixedly connected inside the connecting cylinder, a sliding plate is fixedly connected to the top of the air bag, the sliding plate is slidably connected in the connecting cylinder, a second inclined block is installed on the top of the connecting cylinder, the second inclined block is on the rotation path of the first inclined block, the medicine storage bottle is installed on the top plate of the mixing box, an air guide tube is installed on the bottom of the air bag, the bottom end of the air guide tube is installed on the top of the medicine storage bottle, and a nozzle is installed on the bottom of the medicine storage bottle.

[0011] When the device is running, the motor is started, and the motor drives the stirring rod to rotate in the stirring box to stir the polyurethane raw material in the stirring box, and the output shaft of the motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate together, and then the first inclined block under the driven gear will rotate together with the driven gear, and the first inclined block contacts and squeezes the second inclined block during the rotation process, and the inclined surfaces on the second inclined block and the first inclined block contact each other, and the first inclined block will squeeze downward, causing the airbag to move periodically, and the gas in the airbag will enter the medicine storage bottle through the air guide tube, so that the chemical agent in the medicine storage bottle is squeezed into the stirring box and evenly mixed in the polyurethane raw material by the stirring rod, so that while stirring the polyurethane raw material, the chemical agent is periodically released into the stirring box, so that the agent is mixed in the polyurethane raw material little by little, so that the chemical agent can be mixed with the polyurethane raw material better and faster, thereby increasing the mixing efficiency of the chemical agent.

[0012] Preferably, the adding mechanism also includes an adjusting mechanism and a controlling mechanism, the adjusting mechanism includes a connecting ring, the connecting ring is slidably connected in the connecting tube, an insert ring is slidably connected in the connecting ring, a groove is provided on the connecting ring, a first spring is fixedly connected in the groove, a baffle is fixedly connected to the insert ring, one side of the baffle is fixedly connected to one end of the first spring, a connecting plate is fixedly connected to one end of the insert ring away from the connecting ring, an insert rod is symmetrically fixedly installed on the connecting plate toward one side of the insert ring, and holes are evenly provided on both sides of the connecting tube from top to bottom, and the insert rod is inserted in the holes.

[0013] When producing polyurethanes of different properties, the content of added chemical agents will be different. At this time, the connecting plate can be pulled to pull the plug ring out of the connecting ring, and the connecting plate can be moved up or down as needed. Then the connecting plate is loosened, and the first spring will push the baffle to make the plug ring fit into the gap of the airbag. This will adjust the gas content that can be sprayed out of the airbag each time, thereby controlling the amount of medicine squeezed out of the medicine storage bottle each time, thereby controlling the extrusion amount of the medicine storage bottle.

When the rack rotates a certain number of circles relative to the gear, the rack is completely retracted into the second hollow cylinder and disengaged from the driven gear. At this time, the driven gear will be separated from the second hollow cylinder, and the driven gear will fall down onto the tray, so that the driving gear will be disengaged from the driven gear, and the driven gear will not be able to work, and then the medicine storage bottle will not be able to continue to drip chemicals into the mixing box, thereby achieving control of the amount of medicine.

[0018] Preferably, a liquid inlet pipe is installed through one side of the medicine storage bottle, the top of the liquid inlet pipe extends to the outside of the top of the mixing box, the top of the liquid inlet pipe is threadedly connected to a cover, the top plate of the cover is a transparent color plate, the top of the inner wall of the liquid inlet pipe is rotatably hinged with a color plate, one end of the bottom of the color plate is fixedly connected to a connecting block, a pull rope is hung on the connecting block, and the bottom end of the pull rope extends into the medicine storage bottle and is fixedly connected to a floating block.

[0019] When the medicine storage bottle is not full of chemicals, the floating block moves downward and pulls the color plate to rotate downward. At this time, the color of the lid viewed by the user is the original color of the lid. When the medicine storage bottle is sufficient in chemicals, the color of the lid viewed by the user is the superposition of the colors of the lid and the color plate. This can be used to determine whether the chemicals in the medicine storage bottle are sufficient and remind the user to add chemicals in time.

[0042] The adding mechanism includes a driving gear 7, a connecting tube 11 and a medicine storage bottle 16. The driving gear 7 is fixedly sleeved on the output shaft of the motor 4. The top plate of the mixing box 1 is fixedly connected with a first hollow tube 10. A driven gear 8 is movably sleeved on the first hollow tube 10. The driving gear 7 and the driven gear 8 are meshed with each other. The bottom of the driven gear 8 is fixedly connected with a first inclined block 9. The connecting tube 11 is fixedly connected to the top of the mixing box 1. An air bag 12 is fixedly connected inside the connecting tube 11. A sliding plate 13 is fixedly connected to the top of the air bag 12. The sliding plate 13 is slidably connected in the connecting tube 11. A second inclined block 14 is installed on the top of the connecting tube 11. The second inclined block 14 is on the rotation path of the first inclined block 9. The medicine storage bottle 16 is installed on the top plate of the mixing box 1. An air guide tube 15 is installed on the bottom of the air bag 12. The bottom end of the air guide tube 15 is installed on the top of the medicine storage bottle 16. A nozzle 17 is installed on the bottom of the medicine storage bottle 16.

[0043] When the device is running, the motor 4 is started, and the motor 4 drives the stirring rod 5 to rotate in the stirring box 1 to stir the polyurethane raw material in the stirring box 1, and the output shaft of the motor 4 drives the driving gear 7 to rotate, and the driving gear 7 drives the driven gear 8 to rotate together, and then the first inclined block 9 below the driven gear 8 will rotate together with the driven gear 8, and the first inclined block 9 contacts and squeezes the second inclined block 14 during the rotation process, and the inclined surfaces of the second inclined block 14 and the first inclined block 9 contact each other, and the first inclined block 9 will squeeze downward, so that the airbag 12 produces periodic movement, and the gas in the airbag 12 will enter the medicine storage bottle 16 through the air guide tube 15, so that the chemical agent in the medicine storage bottle 16 is squeezed into the stirring box 1 and is evenly mixed in the polyurethane raw material by the stirring rod 5. In this way, while stirring the polyurethane raw material, the chemical agent is periodically released into the stirring box 1, so that the agent is mixed in the polyurethane raw material little by little, so that the chemical agent can be mixed with the polyurethane raw material better and faster, thereby increasing the mixing efficiency of the chemical agent.

[0044] As an embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 The adding mechanism also includes an adjusting mechanism and a controlling mechanism. The adjusting mechanism includes a connecting ring 18, which is slidably connected in the connecting tube 11. An insert ring 21 is slidably connected in the connecting ring 18. A groove 19 is provided on the connecting ring 18. A first spring 20 is fixedly connected in the groove 19. A baffle 23 is fixedly connected to the insert ring 21. One side of the baffle 23 is fixedly connected to one end of the first spring 20. A connecting plate 22 is fixedly connected to one end of the insert ring 21 away from the connecting ring 18. An insert rod 24 is symmetrically fixedly installed on the connecting plate 22 facing one side of the insert ring 21. Plug holes 25 are evenly provided on both sides of the connecting tube 11 from top to bottom, and the insert rod 24 is inserted in the plug hole 25.

[0045] When producing polyurethanes of different properties, the content of added chemical agents will be different. At this time, the connecting plate 22 can be pulled to pull the plug ring 21 out of the connecting ring 18, and the connecting plate 22 can be moved upward or downward as needed. Then the connecting plate 22 is released, and the first spring 20 will push the baffle 23 to make the plug ring 21 stuck in the gap of the airbag 12. In this way, the gas content that can be sprayed out by the airbag 12 each time is adjusted, thereby controlling the amount of medicine squeezed out of the medicine storage bottle 16 each time, thereby controlling the extrusion amount of the medicine storage bottle 16.

[0046] As an embodiment of the present invention, refer to Figure 6The control mechanism includes a second hollow cylinder 26, which is rotatably connected to the top wall of the first hollow cylinder 10. The top plate and the bottom plate of the second hollow cylinder 26 are rotatably connected to a rotating rod 27 at the center thereof. A connecting rod 30 is rotatably inserted into one side of the first hollow cylinder 10, and one end of the connecting rod 30 extends to the inside of the first hollow cylinder 10. The connecting rod 30 is fixedly connected to one end of the first hollow cylinder 10 with a second bevel gear 29, and the bottom end of the rotating rod 27 is fixedly connected to a first bevel gear 28. The first bevel gear 28 The second bevel gear 29 is meshed with each other, and a rotating handle 31 is fixedly connected to the end of the connecting rod 30 away from the second bevel gear 29. A gear 32 is fixedly connected to the upper end of the rotating rod 27. Two racks 33 are symmetrically slidably penetrated on both sides of the top end of the second hollow cylinder 26 about the center of the top of the second hollow cylinder 26. Both racks 33 are meshed with the gear 32. Both racks 33 are slidably inserted in the driven gear 8. A tray 34 is fixedly sleeved on the first hollow cylinder 10 and the tray 34 is located below the driven gear 8.

[0047] Furthermore, if the overall amount of medicine added needs to be controlled, the rotating handle 31 can be rotated. The rotation of the rotating handle 31 drives the gear 32 to rotate through the meshing between the first bevel gear 28 and the second bevel gear 29, so that the rack 33 meshing with the gear 32 can move in the driven gear 8, and when the driven gear 8 is driven to rotate by the driving gear 7, the rack 33 in the driven gear 8 will rotate relative to the gear 32, and the rack 33 will continuously rotate away from the gear 32 during the rotational meshing with the gear 32. When the rack 33 rotates a certain number of circles relative to the gear 32, the rack 33 is completely retracted into the second hollow cylinder 26 and disengaged from the driven gear 8. At this time, the driven gear 8 will be separated from the second hollow cylinder 26, and the driven gear 8 will fall down onto the tray 34, so that the driving gear 7 is disengaged from the driven gear 8, and the driven gear 8 cannot work, and then the medicine storage bottle 16 cannot continue to drip chemicals into the mixing box 1, thereby achieving control of the amount of medicine.

[0048] As an embodiment of the present invention, refer to Figure 8 The top of the sliding plate 13 is fixedly connected to a connecting frame 40 , a second spring 41 is fixedly connected inside the connecting frame 40 , the top of the second spring 41 is fixedly connected to the bottom of the second inclined block 14 , and the second inclined block 14 is slidably inserted into the connecting frame 40 .

[0049] When the compression height of the airbag 12 is adjusted, to prevent the height of the second bevel block 14 from being still high and blocking the rotation of the first bevel block 9 after the airbag 12 is compressed, the second bevel block 14 will continue to move downward due to the action of the second spring 41 to ensure the normal rotation of the first bevel block 9.

[0050] As an embodiment of the present invention, refer to Fig. 9 and Figure 7A liquid inlet pipe 42 is installed through one side of the medicine storage bottle 16, and the top of the liquid inlet pipe 42 extends to the outside of the top of the mixing box 1. The top of the liquid inlet pipe 42 is threadedly connected to a cover 35, and the top plate of the cover 35 is a transparent color plate. A color plate 36 is rotatably hinged on the top of the inner wall of the liquid inlet pipe 42, and one end of the bottom of the color plate 36 is fixedly connected to a connecting block 37, and a pull rope 38 is hung on the connecting block 37. The bottom end of the pull rope 38 extends into the medicine storage bottle 16 and is fixedly connected to a floating block 39.

[0051] When the medicine storage bottle 16 is not full of chemicals, the floating block 39 moves downward and pulls the color plate 36 to rotate downward. At this time, the color of the cover 35 viewed by the user is the original color of the cover 35. When the medicine storage bottle 16 is sufficient in chemicals, the color of the cover 35 viewed by the user is the superposition of the colors of the cover 35 and the color plate 36. This can be used to determine whether the medicine storage bottle 16 is sufficient in chemicals, and remind the user to add chemicals in time.

[0052] As an embodiment of the present invention, refer to Figure 1 A one-way valve is provided on the air guide pipe 15.

[0053] When the airbag 12 returns to its original state, the one-way valve can prevent the airbag 12 from absorbing the chemical agent in the medicine storage bottle 16 into the airbag 12, ensuring that the medicine storage bottle 16 can normally drip the agent into the mixing box 1.

[0054] Working principle: when the device is running, the motor 4 is started, and the motor 4 drives the stirring rod 5 to rotate in the stirring box 1, stirring the polyurethane raw material in the stirring box 1, and the output shaft of the motor 4 drives the driving gear 7 to rotate, and the driving gear 7 drives the driven gear 8 to rotate together, and then the first inclined block 9 below the driven gear 8 will rotate together with the driven gear 8, and the first inclined block 9 contacts and squeezes the second inclined block 14 during the rotation process, and the inclined surfaces of the second inclined block 14 and the first inclined block 9 contact each other, and the first inclined block 9 will squeeze downward, so that the airbag 12 produces periodic movement, and the gas in the airbag 12 will enter the medicine storage bottle 16 through the air guide tube 15, so that the chemical agent in the medicine storage bottle 16 is squeezed into the stirring box 1 and is evenly mixed in the polyurethane raw material by the stirring rod 5. In this way, while stirring the polyurethane raw material, the chemical agent is periodically released into the stirring box 1, so that the agent is mixed in the polyurethane raw material little by little, so that the chemical agent can be mixed with the polyurethane raw material better and faster, thereby increasing the mixing efficiency of the chemical agent.

[0055] If the overall amount of medicine added needs to be controlled, the rotating handle 31 can be rotated. The rotation of the rotating handle 31 drives the gear 32 to rotate through the meshing between the first bevel gear 28 and the second bevel gear 29, so that the rack 33 meshing with the gear 32 can move into the driven gear 8, and when the driven gear 8 is driven to rotate by the driving gear 7, the rack 33 in the driven gear 8 will rotate relative to the gear 32. At this time, the rack 33 will retract toward the gear 32 as it rotates, until it retracts to the same number of turns as the rotating handle 31, and the rack 33 is completely retracted into the rotating rod 27 and disengaged from the driven gear 8. At this time, the driven gear 8 will be separated from the second hollow cylinder 26 and fall downward onto the tray 34, so that the driving gear 7 is disengaged from the driven gear 8, and the driven gear 8 cannot work, and then the medicine storage bottle 16 cannot continue to drip chemicals into the mixing box 1, thereby achieving control of the amount of medicine.

At this time, the connecting plate (22) is pulled to pull the insert ring (21) out of the connecting ring (18), and the connecting plate (22) is moved upward or downward as required. Then, the connecting plate (22) is loosened, and the first spring (20) pushes the baffle (23) to make the insert ring (21) fit into the gap of the air bag (12). In this way, the gas content that can be sprayed out of the air bag (12) each time is adjusted, thereby controlling the amount of medicine extruded from the medicine storage bottle (16) each time, thereby achieving control of the extrusion amount of the medicine storage bottle (16); When the total amount of the medicine to be added needs to be controlled, the rotating handle (31) is rotated. The rotation of the rotating handle (31) drives the gear (32) to rotate through the meshing between the first bevel gear (28) and the second bevel gear (29). In this way, the rack (33) meshing with the gear (32) can move in the driven gear (8). When the driven gear (8) is driven to rotate by the driving gear (7), the rack (33) in the driven gear (8) rotates relative to the gear (32). The rack (33) is constantly rotating and meshing with the gear (32). When the gear (32) is rotated away and the rack (33) rotates a certain number of times relative to the gear (32), the rack (33) is completely retracted into the second hollow cylinder (26) and is separated from the driven gear (8). At this time, the driven gear (8) is separated from the second hollow cylinder (26), and the driven gear (8) falls downward onto the tray (34). In this way, the driving gear (7) is disengaged from the driven gear (8), and the driven gear (8) cannot work, and the medicine storage bottle (16) cannot continue to drip the chemical agent into the mixing box (1), thereby achieving the control of the amount of the medicine.
